I made a newton interferometer, simple construction with a strip of red leds, the self adhesive ones. The power supply of 12 volt is from an adjustable power supply I bought for the ronchi test rig and a led from jaycar. I later will use it for an autocollimation test stand as described on Stelllafane. That is for me the simplest. I started out with diffusing a laser light, but promptly zapped it when I forgot what voltage I had the power supply on. I can make you a drawing of the interferometer if you would like.
